Lub teeb tuaj yeem xav tias yog "particle" ntawm electromagnetic zog hu ua photons. Txij li thaum lub zog nce raws li tus zaus nce, lub zog yog ncaj qha proportional mus rau zaus . Vim zaus thiab wavelength muaj feem cuam tshuam los ntawm qhov tsis tu ncua (c) lub zog kuj tuaj yeem sau tau raws li lub wavelength: E = h · c / λ.
Tib neeg kuj nug, dab tsi yog zaus inversely proportional rau?
Qhov tseem ceeb zaus ntawm ib txoj hlua vibrating yog inversely proportional rau nws ntev. Txo qhov ntev ntawm txoj hlua vibrating los ntawm ib nrab yuav ua rau nws ob npaug zaus , tsa lub suab los ntawm ib qho octave, yog tias qhov nro tseem zoo li qub.
Ib tug kuj yuav nug, qhov kev sib raug zoo ntawm zaus thiab suab yog dab tsi? Ib siab suab suab sib raug rau siab zaus suab yoj thiab qis suab suab sib raug mus rau qis zaus suab yoj. Amazingly, ntau tus neeg, tshwj xeeb tshaj yog cov uas tau kawm suab paj nruag, muaj peev xwm txheeb xyuas qhov sib txawv hauv zaus ntawm ob lub suab sib cais uas tsawg li 2 Hz.
Ib yam li ntawd, nws raug nug, yog zaus thiab wavelength ncaj qha proportional?
Lub wavelength feem ntau yog xaiv los ntawm Greek tsab ntawv lambda (λ). Piv txwv li lub sinusoidal nthwv dej txav ntawm lub nrawm nrawm, wavelength yog inversely proportional rau zaus ntawm nthwv dej: nthwv dej nrog siab dua zaus muaj luv dua wavelengths , thiab qis zaus muaj ntev wavelengths.
Dab tsi yog qhov kev sib raug zoo ntawm zaus thiab wavelength ncaj qha lossis thim rov qab?
Ntau zaus thiab wavelength muaj ob leeg ncaj qha thiab inverse kev sib raug zoo . Piv txwv li, yog tias ob lub nthwv dej taug kev ntawm tib lub nrawm, lawv yog inversely ntsig txog. Lub nthwv dej nrog luv wavelength yuav muaj siab dua zaus thaum ntev wavelength yuav muaj qis dua zaus.

Dab tsi yog proportional ncaj qha rau nruab nrab kinetic zog?
Qhov nruab nrab kinetic zog ntawm ib qho kev sau ntawm cov pa roj yog ncaj qha proportional rau qhov kub thiab txias nkaus xwb
Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev taw qhia ntawm tes los ntawm kev sib cuag lub cev ncaj qha?
Kev taw qhia kuj tshwm sim ntawm cov hlwb uas yog kev sib cuag ntawm lub cev. Kev sib cuam tshuam ntawm cov proteins ntawm qhov chaw ntawm cov hlwb tuaj yeem ua rau muaj kev hloov pauv hauv cov cwj pwm ntawm tes. Piv txwv li, cov proteins nyob rau saum npoo ntawm T-cells thiab antigen nthuav tawm cov hlwb sib cuam tshuam los ua kom muaj kev taw qhia hauv T-cells
Tus qauv hloov pauv ncaj qha yog dab tsi?
Thiab cov qauv rau kev hloov pauv ncaj qha yog y = kx, qhov twg k sawv cev rau qhov hloov pauv tsis tu ncua. Cov tub ntxhais kawm kuj kawm tau hais tias cov qauv ntawm kev hloov pauv ncaj qha, y = kx, yog ib txoj kab ua haujlwm, qhov nqes hav yog sib npaug rau k, thiab y-intercept yog sib npaug rau 0
Lub hnub ncaj qha thiab tsis ncaj qha cuam tshuam li cas rau qhov kub thiab txias?
Lub hnub ncaj qha los tsoo lub ntiaj teb saum npoo ua rau muaj qhov kub thiab txias dua li lub hnub ci ncaj qha. Lub hnub ci dhau los ntawm huab cua tab sis tsis sov nws. Tsis tas li ntawd, lub teeb lub zog los ntawm lub hnub tsoo cov kua thiab cov khib nyiab ntawm lub ntiaj teb. Lub hnub ci poob sib npaug ntawm lawv txhua tus
Cov txheej txheem dab tsi hloov pauv ncaj qha rau hauv vapor?
Sublimation yog cov txheej txheem uas cov khoom hloov pauv ncaj qha mus rau hauv vapors lossis gaseous xeev yam tsis dhau los ntawm cov kua hauv lub xeev
